The Basics about Bird Flu

By Groshan Fabiola

Avian influenza is a natural infection in wild birds, which are actually carriers without ever being affected by the disease. Never the less, the avian flu can be passed to domestic poultry through various types of contact such as sharing the same food and water or coming in contact with excrements and cages of contaminated birds. A fairly easy way of determining whether poultry such as chicken, ducks, turkeys has bird flu is microscope examination of their saliva and nasal secretions.

Bird flu caused by influenza A viruses does not have a spontaneous effect on humans. The possibility is rather low to many because we are not as susceptible to it as birds. Though rare, cases of human infection have been outlined by the press. The virus that spreads among humans is known as the human influenza virus and has three branches: H1N1, H1N2, H3N2. The viruses vary through the different types of proteins that form their genetic coat: Hemagglutinin and Neuraminidaze. Parts of the virus affecting humans have also been found in birds, but the main concern is that the virus is in permanent replication and may one day evolve into a more potent form.

Furthermore, there are two forms of influenza, differing through pathogenic capacity. The low form is usually not easily spotted and can cause minor derangements, while the high extremes of virulence are much more dangerous leading to high death ratio and damaging vital body parts.

Moreover, the H5N1 virus or the influenza A virus has affected a number of people. For this reason, it is becoming a nuisance in undeveloped regions of Asia and Africa where poverty is widespread and living conditions are at a limit. In these places transmission between different species of birds and bird to human transmission is very likely because people live in very close contact with their poultry. Generally the following manifestations are present: conjunctivitis, pneumonia, breathing disorder, fever, cough, sore throat, muscle aches.

Although researchers are trying to come up with a vaccine as fast as possible, further experiments with the genetic coat of the virus are a must for the cure to be efficient. However, medication does exist. The likes of Zanamavir and Oseltamavir are currently on the market but it is not known whether they work or not.

At present time nobody can tell 100% if bird flu can cause a pandemic, but the H5N1 virus is closely monitored by experts worldwide.
